ST series hydrophone cable streamer is designed for seismic refraction surveys at longitudinal (P-) waves. The hydrophone modules utilize high sensitive piezoceramic sensors. The default number of modules on the hydrophone cable is 12 or 24, but it can vary from 1 to 48. The standard interval between the hydrophone and the lead-in cable length at the end is 10m, 20m but can vary upon the client’s requests.
